A spike is a sharp rise in blood sugar after eating. A swing is when glucose goes up and then crashes down—often leaving you tired, shaky, or hungry again.
Why?
Because it’s not just the high number that matters—it’s how fast you get there and what happens after. Big spikes and wild swings put more stress on the body than slower, steadier rises.
The Catch?
Not every spike is a failure. Some foods spike fast but settle quickly. Others don’t spike much… but lead to long, drawn-out swings. Context matters.
The Takeaway
The goal isn’t zero spikes—it’s fewer roller coasters. Aim for smoother curves, gentler rises, and quicker recoveries. Progress lives in the trends, not the moment.
